Hi there-
Working on duplicating some systems here. I don't want to use perl CPAN shell to install modules because the modules on three systems need to be the same version and I don't want to download new versions
I have system 1 which is a "master" and systems 2 and 3 which are "clone" that has just been built.
I used instmodsh to create a tar file of a module from system 1 (Text::Glob). I untarred it on system 2. It sees it , but i want to instmodsh to be able to see it.
How do I do this?
Here is the detailed version:
log into system 1
instmodsh
m Text::Glob
t testglob.tar
(quit)
transfer file to system 2
cd /
tar xvpf testglob.tar
I did this perl executable to test:
#/usr/bin/perl
use Text::Glob;
and it worked on both server 1 and server 2 . Just in case I tried it on server 3 where I did not untar the textglob.tar and it errored on server 3 as expected
However, instmodsh with list option shows Text::Glob installed on server 1 but not on server 2.
I'm guessing this will be related to rebuilding /root/.cpan in someway as well.
Help please?
Thanks!

The instmodsh uses ExtUtils::Installed to get information about what modules are installed. This module uses the .packlist file in the module directory. So, to have instmodsh show the module as installed, you need to look on system1 in your @INC directories for Text/Glob/.packlist, and copy this to system2.
Thanks for the tip in the packlist.
Any ideas about the root cpan? Should I just delete it and then run perl -MCPAN -e shell and see if it rebuilds?
What does perl look at to rebuild the cpan database?
Oh I also concatened the perllocal files so that perldoc perllocal sees the changes
Thanks for the help so far!
I would like the clan databas to reflect the modules installed in /usr/lib/perl5 .. So if I copy anything into /usr/lib/perl5 , how do I get clan to update? So I was thinking just delete the entire .cpan dir and then running perl -MCPAN -e shell would rebuild .cpan as if it was rebuilding for the first time .. I'll try this. Think it will work?

uayneb,
I am not an expert when it comes to building install packages and dealing with CPAN. And, it might get worse that it appears, because some module installs require some C code to be compiled, which will not happen during a copy, and might end up being a problem.
So, if I had this problem, I would go to cpan.org and download the version that I needed. And then, follow the install doc for each, which is usually:
perl Makefile.PL
make
make test
make install
So, for Text::Glob, just click on the link with the version in it, and use the dropdown on that page to select your version:
Richard Clamp > Text-Glob-0.08 > Text::Glob
click ^^^ here
I know it is not exactly what you were looking for, but, I think it might get you to the same place...
